Engines may experience ingress of coolant to the fuel system or vice versa due to the degradation of the sleeve seal-o-rings and the unit injector seal-o-rings. The contamination of coolant into the fuel system affects engine performance and can cause injector seizure. Contamination of fuel in the cooling system may reduce cooling performance.
